Gospel of Truth - gnostic writing

The Gospel of Truth is one of the Gnostic writings discovered at Nag Hamadi.
Nag Hamadi is a location in Egypt where thirteen ancient books were found in 1945, and translations of these books were finally completed in the 1970s. Along with the Gospel of Truth, the Nag Hamadi library (as it has come to be called) also contains the more well-known Gospel of Thomas and the Gospel of Philip.
